    See the below facts
    40% of America's rivers are too polluted for fishing, swimming, or aquatic life.
    Even worse are America's lakes—46% are too polluted for fishing, swimming, or aquatic life.
    1.2 trillion gallons of untreated sewage, storm water, and industrial waste are discharged into US waters annually. The US EPA has warned that sewage levels in rivers could be back to the super-polluted levels of the 1970s by the year 2016.
    Asian rivers are the most polluted in the world. They have three times as many bacteria from human waste as the global average and 20 times more lead than rivers in industrialized countries.

    "The livestock sector is a key player in increasing water use, accounting for over 8 percent of global human water use, mostly for the irrigation of feedcrops. It is probably the largest sectoral source of water pollution, contributing to eutrophication, “dead” zones in coastal areas, degradation of coral reefs, human health problems, emergence of antibiotic resistance and many others. The major sources of pollution are from animal wastes, antibiotics and hormones, chemicals from tanneries, fertilizers and pesticides used for feedcrops, and sediments from eroded pastures."
